    <p>ios 7 with ringtone software does not work. ios 5 and ios 6 are working properly. When I run it with ios 7, duration of the ringtone is the same as the source file is created. Needs to be 40 sec. but it seems to 300-400 seconds.</p> <pre><code>- (void)Convert{ AVURLAsset *songAsset = [AVURLAsset URLAssetWithURL:self.audioplayer.url options:nil]; AVAssetExportSession *exporter = [[AVAssetExportSession alloc] initWithAsset: songAsset presetName: AVAssetExportPresetAppleM4A]; //exporter.outputFileType = @"com.apple.m4a-audio"; exporter.outputFileType = AVFileTypeAppleM4A; CMTime start = CMTimeMakeWithSeconds(self.audioplayer.currentTime, 1); CMTime duration = CMTimeMakeWithSeconds(40, 1); CMTimeRange range = CMTimeRangeMake(start, duration); exporter.timeRange = range; NSString *exportFile = [[self kDoc_dosya:self.name] stringByAppendingPathExtension:@"m4r"]; if ([[NSFileManager defaultManager] fileExistsAtPath:exportFile]) [[NSFileManager defaultManager] removeItemAtPath:exportFile error:nil]; NSURL *exportURL = [NSURL fileURLWithPath:exportFile]; exporter.outputURL = exportURL; [exporter exportAsynchronouslyWithCompletionHandler:^{ int exportStatus = exporter.status; switch (exportStatus) { case AVAssetExportSessionStatusFailed: { NSError *exportError = exporter.error; NSLog (@"AVAssetExportSessionStatusFailed: %@", exportError); break; } case AVAssetExportSessionStatusCompleted: { NSLog (@"AVAssetExportSessionStatusCompleted--"); break; } case AVAssetExportSessionStatusUnknown: { NSLog (@"AVAssetExportSessionStatusUnknown"); break;} case AVAssetExportSessionStatusExporting: { NSLog (@"AVAssetExportSessionStatusExporting"); break;} case AVAssetExportSessionStatusCancelled: { NSLog (@"AVAssetExportSessionStatusCancelled"); break;} case AVAssetExportSessionStatusWaiting: { NSLog (@"AVAssetExportSessionStatusWaiting"); break;} default: { NSLog (@"didn't get export status"); break;} } }]; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
